Rear Refractory Replacement Procedure – Continued
IMPORTANT
If the rear refractory (part no. 83027) was damaged during removal, it
should be replaced with a new part. If rear refractory replacement is
required, a 2 hour burn-in period at a 30% fire rate must be performed to
drive off organic binders. These organic binders are not hazardous
materials, however they may emit an odor similar to burning wood.
15. Tighten the bolts on the rear plate using an alternating pattern to ensure a uniform seal.
Torque bolts to approximately 20 ft-lbs.
16. To avoid exhaust leaks, ensure that a uniform seal is established when reconnecting the
flue system to the boiler.
